High-function heat transfer releases
View Patent ↗A heat transfer label is disclosed. The heat transfer label comprises a special heat stable release which strongly adheres to the carrier, offers a highly ink and adhesive wettable surface, stays intact under heat transfer bonding conditions, releases easily, leaves no contamination on the transfer or fabric, and enables durable replication of the release surface finish onto the resultant transfers.
